T u all whom. it may concern:

lie it known that l. llnunax Manama, n tltlZtll of the United States of America. residing at Jackson, in the county of Jackson and State of Michigan. have invented certain new and useful Improvements in Combined Routers and Die-Sinkers; and I do hereby declare the following to be a full, clear. and exact description of the invention. such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in combined routing and die sinking machines and its object is to provide a machine adapted to alternately operate a rotary routing tool and an oscillating die sinking tool; to provide improved means for operating the die sinking tool; to provide means for readily moving the routing tool into and out of operative position, and to provide the device with various new and useful features hereinafter more fully described and particularly pointed out in the claims, reference being had to the accompanying drawings, in which:-

Figure l is a front elevation of a machine embodying my invention; Fig. 2 a side elcvation of he samc:--Fig. 3 a rear elevation of a portion of the same: Fig. 4 a plan view of the same with the bed omitted; Fig. 5 a detail of the rack and pinion mechanism of the die sinking tool shown partly in elevation and partly in section; Fig. 6 a front elevation in detail of the mechanism for the vertical and lateral movement of the die sinking tool in position for the back stroke; Fig. 7 the same in position for the cutting stroke; Fig. 8 a detail partially in plan and artially in horizontal section taken on the line 88 of Fig. 6; Fig. 9 a detail partially in vertical section showing the sliding attachment to the frame of the mechanism for operating the die sinkin tool; Fig. 10 a dctail in vertical section 0 a portion of the (lie sinking mechanism; and Fig. 11 a detail of the cam wheel.

Like numbers refer to like parts in all of the figures.

represents the frame of the machine, B the bed to which the work is secured in the usual way. said bed having the usual vertical and horizontal movements to move the work in all directions relative to the tools.

I is a horizontally disposed main driving shaft at the top of the 'frame. 2 a cone pulley driven by any suitable belt in the usual manner. 3 a vertical spindle carrying anv suitable routing tool 4 at its lower end and journled in arms 5" mounted on a swinging nu-mber 5 hinged at one side to the frame as at ti and secured in operative )osit'ion h screws or other fastenings T. 'l iis spiudlz is driven by miter gears H. one on the driving shaft and one on the spindle. which gears are engaged when the spindle is in operative position. When the routing tool is out of use the fastenings 7 are removed and the s )indle swung out of the way of the work as illustrated in Fig. 4.

9 is a housing for the die sinking tool having a semi-circular channel 9" in which is slidahly supported a segment shaped tool holder 1.0 in which is mounted a suitable die sinking tool 11 having suhstuntinllv a circular head with cutting teeth on its sides and periphery. the axis of which too] is located in the axis of the segmental holder. The periphery of this holder is provided with a segmental pinion 3T engaged by a rack 36 to oscillate the holder in the casing. channel 9" is provided in the to of the casing in which the rack 36 is slidab c.

if. is a vertically disposed dove-tailed way tixcd on the frame on which way is a vertically movable slide 15 having a horizontal dove-tail way on which is slidablc an arm 16 support ing the housing 9. The housing is thus mounted on the frame to move either \erticallv or horizontally by means of these ways am slide. The housing is sn ported and moved vertically by a togge ever 14 pivoted to the housing at its lower end and to an arm 13 on the frame at its upper end.

17 is a rock shaft journalcd in hearings on the frame and having a yoke IS mounted on-its forwln'd end supporting the ends of an oscillating rod H on which is a slide 30 pivotally conn cted to a rnrrc wruiing slide 21 mounted on a vertically disposed rod '2'. on the arm i i, the slides 20 and 21 being vertically adjustable by means of a pin 37! in the slide 21 engaging anv one of a series of holes in the arm lti. liv adjusting the Sllt'lth' opposite the end of the rock shaft no horizontal movement of the housing is produced. liv tltljlhtli'l}: the slides above or below said sha ft at greater or less distance,

more or less horizontal movement of the housing is produced on the forward stroke,

if adjusted at one side of the shaft and on the back stroke if adjusted at the other side of the shaft.

24 is an arm extending upward from the yoke 18 and 25 a connecting rod pivoted to the end of the arm at one end and to the middle joint of the toggle lever 14 at the other end, whereby the housin is raised and lowered as the yoke is oscill ated.

26 is an arm fixed on the rock-shaft. at one end and having a stud 27'at the other end engaging and traversin a groove 28 in a cam wheel 29. This whee 15 provided with a crank pin 30 on which is journaled a slide 31 ada ted to traverse an arm 32 fixed on a rock s aft 33 whereb the rock shaft is given an oscillating an quick return movement.

34 is an arm on the rock shaft and 35 a connecting rod which connects the arm 3% with the rack 36 operatin the segmental holder 10. The cam whee 29 is mounted on a shaft 39 driven from the driving shaft 1 by means of a vertical shaft 38, bevel cars 40 and miter gears 41 as shown in Fig. 3.

In operation when the routing tool 4 is in use the gear 41 on the shaft 39 is moved out of engagement with the gear 41 on the shaft 38 and thus the die sinking mechanism put out of action. When its work has been completed. the routing tool can then be swun out of the way, the gears 41 retinga e and the work adjusted by raising and moving the bed B to be properly engaged by the die sinking tool 11. On the forward stroke the upper end of the yoke 18 is oscillated toward the toggle lever whereby the same is operated to lower the tool into engagement with the work and at the same time the slides 20 and 21 bein adjusted above the axis of the rock sha 17 will adjust the tool laterally during the forward movement of the cutting stroke as in -Fig. 7. On the return stroke the yoke 18 beingi oppositely oscillated will raise the tool an move it laterally out of engagementwith the work as illustrated in Fig. 6. If it is desired to operate the tool in reverse relation to the work all that is necessary is to adjust the slides 20 and 21 below the axis of the rock shaft 17. The side movement of the tool will thus be reversed, thus engagin the opposite side of the tool with the wor to cut in the opposite direction.
